Speed = Distance divided by Time.
So, speed = 75 miles divided by 2.5 hours = 75 / 2.5 = 30 miles per hour.
Velocity is speed and direction, so the velocity is 30 mph Northbound.
Watch closely:
75/25 = 3 miles per hour, north
Blah
Velocity = 790.514 m/s North (rounded)The idea is to divide the distance by the time.
3.00 m/s
The resultant velocity of a plane is 125 km/hr.
We're not completely sure what you mean by "per hour per second". Going just by what we see in the question, it's an acceleration, not a velocity. "Six miles per hour north" would be a velocity.
exacly 25
Divide the distance by the time to get the speed. The direction, of course, is north-east.
Velocity is speed and direction. The velocity would be zero because the 50 miles N cancel the 50 miles S. The speed is 100 mi/5 h = 20 mph.
average velocity = miles/hours = (100 + 30)/(2 + 1) = 130/3 ≈ 43.33 miles/hour
Average speed = Total Distance/Total Time = (15+25)/2 = 40/2 = 20 miles per hour. Velocity (due North) = Total NET distance North/Total Time = (15-25)/2 = -10/2 = -5 miles per hour or, velocity due South = 5 miles per hour.
Velocity is speed and its direction. "30 miles per hour" is a speed. "30 miles per hour north" is a velocity". "30 miles per hour north" and "30 miles per hour south" are identical speeds but different velocities.
Speed is the size of velocity. But velocity also has a direction. "30 miles per hour" is speed. "30 miles per hour north" is velocity.
Velocity = 790.514 m/s North (rounded)The idea is to divide the distance by the time.
Yes. Velocity is a vector and therefore requires magnitude and direction: Magnitude: 100 kph Direction: North
25 miles.
3.00 m/s
Speed is a scalar and velocity is a vector. A scalar only has magnitude while a vector has magnitude and direction. Example: If you are traveling north at 65 miles an hour your speed is 65 miles an hour, your velocity is 65 miles an hour north. It gets a little more complicated. Speed = distance (a scalar)/time Velocity = Displacement (vector)/time Example: If you run 5 miles in an hour left and then 5 miles in a hour right your speed is 10 miles/2 hours = 5 miles an hour. However, since you end up in the same exact location as where you started your displacement is zero making your velocity zero as well. Think of it this way; since velocity is a vector it requires a direction if i ended up exactly where I started I have no direction, thus velocity must be zero. One more example to clarify: If you ran 6 miles right and 4 miles left in 2 hours, your speed will be 5 miles an hour (10/2=5) your velocity would be 1 mile an hour to the right, since displacement is 2 miles to the right (6 to right - 4 to left = 2 to right) and the time is 2 hours displacement/time = velocity; 2 to the right/2 = 1 mile to the right per hour.
10 miles per hour speed is not a vector quantity, therefore direction does not matter. 16 miles/ 2 hours=8 mph 24 miles/ 2 hours=12 mph (8+12)/2=10 mph average
